The area in a fifth wheel RV where the electronics, plumbing & other items are located is called by many the basement.
Working in that area is cramped and poorly lit. Short of loosening weight I can’t do anything about the cramped but I did add work lights to help with the lighting. This video deals with my latest update to my work lights and shows how I installed the work lights.
